        <p>
          This demonstrates the implementation of a custom HTML context menu using <a>HTMLInfo</a>.
          This sample is also a re-implementation of the built-in <a>ContextMenuTool.defaultTouchContextMenu</a>.
        </p>

        <p>The implementation is contained in the files <a href="../extensions/LightBoxContextMenu.js">LightBoxContextMenu.js</a> and <a href="../extensions/LightBoxContextMenu.css">LightBoxContextMenu.css</a>. The JavaScript file exposes <code>window.myHTMLLightBox</code>, which is used in this file as the value of <code>myDiagram.contextMenu</code>.

        <p>For a more regular HTML context menu implementation, see the <a href="customContextMenu.html">Custom Context Menu</a> sample.</p>
        <p>Right-click or tap-hold (mobile) on a Node to bring up a context menu.
           If you have a selection copied in the clipboard,
           you can bring up a context menu anywhere to paste.</p>
